If there's an interesting plot premise, perhaps something a touch different or slightly weird, that would draw me enough for me to want to see how it plays out. But I think one thing that really draws me in is interesting characters, because a lot of plots have been done, or new ones are variations on an old formula. So, give me an interesting character and I'll want to read on - to find out how they react to certain situations they're put in. For example, it can be hugely entertaining to have a character who's usually sarcastic and a touch apathetic put in highly serious situations.
